Scientists believe humans will be able to live forever after downloading their brains to a computer hard drive.
It opens up the possibility of eternal life – but not as we know it.
Neuroscientist Dr Hannah Critchlow says that if a computer could be built to recreate the 100 trillion connections in the brain, it would be possible to exist inside a programme.
The brain is enormously complex but it works like a giant circuit board and experts are beginning to understand the function of each part.
Dr Critchlow, from Cambridge University, said: “If you had a computer that could make those 100 trillion circuit connections then that circuit is what makes us us, and so, yes, it would be possible.
“People could probably live inside a machine. Potentially, I think it is definitely a possibility.”
She has also shot down the myth that humans only use 10% of their brains.
